Custom validation with Sequelize

Hi,i'm trying to get custom validation on one column of my model:In my model definition:var Device = sequelize.define('Device', { model_name: DataTypes.STRING, imei: DataTypes.STRING, serial_number: { type: DataTypes.STRING, validate: { customValidation(value) { Device.findOne({ where: {serial_number: value} }) .then(function() { throw new Error('serial number already exists!') }) } } } Record creation:Device.bulkCreate(csvOutput, { validate: true }) .then(function() { console.log('Records inserted into database') }) .catch(function(err) { console.log('Error encountered: ' + err) }) When I try to insert duplicate entries, the validation seemed to pick it up - I could see the 'serial number already exists!' message on the terminal, but the records ended up being inserted into the db anyway.Can someone point out where i've gone wrong?
